How did you 'rectify' it though? By using the modern day ranking system?

And go week by week? Even I hardly have such time. With Connors, he at least split with Ashe in '75, so I gave Ashe 27 weeks, one week over half. I gave 14 to Vilas, one week more than 1/4 of the season in '77.

For Lendl, his numbers from 89 and 90 are a bit screwy. Becker was the true year end in 89, and I awarded him an extra 20 weeks, and for Edberg, I gave him 13 from Lendl, another 1/4 of the season. Have you an alternate method?
